What are Platonic Solids?
In three-dimensional space, a Platonic solid is a regular, convex polyhedron. It is constructed by congruent (identical in shape and size), regular (all angles equal and all sides equal), polygonal faces with the same number of faces meeting at each vertex. Five solids who meet this criteria are Tetrahedron {3,3} , Cube {4,3} , Octahedron {3,4} , Dodecahedron {5,3} , Icosahedron {3,5} ; where in {p, q}, p represents the number of edges in a face and q represents the number of edges meeting at a vertex; {p, q} is the Schläfli symbol.
How to Calculate Perimeter of Icosahedron given Insphere Radius?
Perimeter of Icosahedron given Insphere Radius calculator uses Perimeter of Icosahedron = (360*Insphere Radius of Icosahedron)/(sqrt(3)*(3+sqrt(5))) to calculate the Perimeter of Icosahedron, The Perimeter of Icosahedron given Insphere Radius formula is defined as the sum of the total distance around all the edges of the Icosahedron and is calculated using the insphere radius of the Icosahedron. Perimeter of Icosahedron is denoted by P symbol.
